INVENTOR UEL M-CAUDE-LL UEL M. C'AUDELL, OF EVAN SVILDE, INDIANA.

ACETYLENE-GAS GENERATOR.

Specification of Letters Patent.

Patented July 1 1-, 1914.

Application filed. March 1, 1913. Serial No. 751,605.

To all whom it may concern:

Be it known that I, UEL M. CAUDELL, a citizen of the United States,residing at Evansville, in the county of Vanderburg and State ofIndiana, haveinvented certain new and useful Improvements inAcetylene-Gas duction of an efiicient means for feeding; carbld into thetank member when the gas.

within the expansion bell reaches a low pressure.

Another object of this invention is the pro- I duction of an eflicientfeeding mechanism 1 which is adapted to discharge a certain quantity ofcarbid into the tank when the gas therein reaches a low pressure.

With these and other objects in view this invention consists of certainnovel combinations, constructions, and arrangements of parts as will behereinafter fully described and claimed.

In the accompanying drawings :-Figure.

1 is a central vertical section of the generator showing the carbidcontainer and mechanism in elevation. Fig. 2 is a perspective view ofthe carbid container and feeding mechanism. Fig. 3 is a central verticalsec-. t10n of the carbld contamer and mechanism.

Fig. 4: is a section taken on line 4-4t of Fig. 1, looking in thedirection of the arrow.

Referring to the accompanying drawings. by numerals it w1ll be seen thatthis 1nvention consists of .a well 1 which carries the hood 2. Slidablymounted within this well,

1 is an expansionbell 3 which carries the apertures formed in the chute7 as 1llushandle 4.

When it is desired to fill the carbid container the hood 2 is removed atwhich time the bell 3 may be taken from within the well with the well 1a sealing chamber for the hell.

3, as illustrated in Fig. 1. The lower portion of this body 5 isprovided with an inclined chute 7 which carries on its lower side thesubstantially U-shape guiding frame 8. The body 5 is also provided withthe depending arms 9 which are pivotally connected to the operating arms10 by means of the bolt 11. These operating arms are spread at theirforward ends, as illustrated in Fig. 2, whereby to be placed upon eachside of the chute 7, and in order to hold the same in their correctposition there are provided a plurality of bolts 12. The forward portionof the operating arms 10 are provided with the upwardly extendingsupporting members 13 which are provided with the slots 13 which carrythe door 14 by means of the retaining members 15 fitting within theslots 13. The downward movement of this door 14 is limited by means ofthe lips 16, whereby passage of the chute will be closed. Adjacent theforward portion of the arms 10 there is provided a U-shape bracket 17which carries the upwardly extending fingers 18.

The chute 7 is provided with a partition 34 having a supporting portion34 constituting a pocket 35. By forming the supporting portion andpartition within. the chute so as to form a pocket, the fingers 18 willbe allowed to pass in front of said pocket as the door is opened. If nopartition were used, the carbid would become so jammed within the chute7 as to render the passing of the fingers 18 very difficult or nearlyimpossible, as the fingers could not force the carbid to one side butwould jam the same against the top of the chute. From the foregoingdescription it will be seen that the fingers 18 are first passed upthrough the trated in Fig. 4 and then through the carbid containedwithin the chute 7 until the end portions of the fingers18 pass in frontof the pocket 35. The members 15 will then be engaged by the portion ofthe members 13 adjacent the end of the slots 13. The door will then beraised whereby the carbid can drop into the well. The rear portion ofthe arms 10 carry the link 19 upon which the arm 20 is pivotallymounted. This arm 20 carries at its upperend the head 21 which isengaged by the upper portion of the expansion bell 3 when the samelowers, whereby the member 20 will be pushed down and will in thismanner raise the forward portion of the operating arms 10. It will beseen that since the door 14 normally remains in a closed position thecarbid contained within the member 5 will pass down the chute 7 so as torest against the door 14. When the door is raised, the fingers 18 havepassed. up into the chute so as to prevent all the carbid containedwithin the member 5 from passing therethrough, thereby allowing only apredetermined charge or amount to be fed into the well. weight of themember 20 and the head 21 there is provided a weight 22 forthis purose.p It will be seen that the well 1 is mounted within the cement casing 23whereby the water contained therein will be prevented. from freezing.There is also positioned within this cement casing 23 an upwardly.

extending pipe 24. This pipe as carries at its upper end the pump 25adjacent which 1s formed the discharge pipe '26. It will be seen that bythis means the residuum which is contained within the. well may be takentherefrom by means of the pump while the pipe 24,- will allow air toreturn into the well. Upon the opposite side of the Well 1 there is agas filter pipe 27.

When it is desired to remove the hell 3, is will be necessary to allow aquantity of air. to pass'under the bell. This is accomplished byturningon the valve 36 at which time the air will pass therethrough tothe pipe 32 downwardly through the check valve 37 and pipe 38. Air willthen pass into a secondary air pipe-39 by means of the secondarystopcock 4,0. This pipe 39 isprovided with an elbow 4E1 which connectswith the gas conduit pipe 27. This pipe 27 passes up into the gas bell3' whereby the air will pass into the bell and will allow the same to beeasily removed when it is desired to fill the carbid container.

When the hell 3 moves down so as to bear upon the head 21, the door 14;will be raised so as to allow a quantity of carbid to fall .into thewater contained in the well. The gas will then pass up around the carbidcontainer and will pass into the bell 3 through the/apertures 42 formedin the cylindrical casing 6. When the pressure within the bell raisesthe same, the pressure is sufficient-to force the gas from the interiorof the bell, the gas will pass down through the conduit pipe 27. Itwill, however, be impossible for the gas to pass into the pipe 38 bymeans of the pipe 39 since the stopcock 40 will prevent the passage ofthe gas therethrough. so as to bubble through the water contained in thegas chamber 29. The lower end of the pipe 38 communicates with the gaschamber 29, as illustrated at 38'. This pipe 38 is also provided withthe check valve 37 whereby the pressure of the 1 gas will forcev Inorder to counterbalance the' The gas will continue down the same throughthe supply pipe 28 and into the house or any desired place.

The well 1 is provided with an inclined bottom 29 which is adapted toform the top for the gas chamber 29. This bottom 29 will shift theresiduum in the lower portion of the well toward the pipe 24wherethrough it may be discharged. In order to free the gas of anysediment, the gas is forced from the bell through the pipe 27 and thewater in the gas chamber 29, the gas being cleansed by the water inthegas chamber 29 since this water is not contaminatedwith the water in thewell 1. The water may be supplied to the gas chamber 29 by means of thepipes 32 and 38 since the pipe 38 communicates with the gas chamber 29as shown at 38;

From the foregoing description it will be seen that a generator has beenproduced which will efficiently generate a quantity of gas and willforce the same into a system, and which is also provided with a meansfor allowing the same to be easily refilled or for allowing the residuumto be cleaned from the lower portion.
